Why plop

Made for mess. Designed like it isn't.

Naomi, Founder

"I'm making plop for my two boys, and for every other kid who refuses to be anywhere but outside. Their clothes and books came home sodden too many times; I wanted a bag that could keep up."

Rain stays out.
A wide roll top folds down and seals the whole opening, so books and snacks stay dry in a downpour.
Mud wipes off.
The soft matte TPU fabric takes puddles, park benches and mud. One wipe and it looks new again.
10L that fits the day.
Big enough for A4 books, a lunch box, spare clothes and a water bottle, with room left for conkers.
Easy for small hands.
Roll, press, done. Padded straps and a chest strap that a three-year-old can manage alone.
Built to last years, not seasons.
Soft matte TPU fabric, fully waterproof, with welded seams, a reinforced base and premium fastenings. Made to outlast the usual kids' bag.
